____________________________
The resistance of an object (i.e., a resistor ) depends on its shape and the material of which it is composed.
Resistivity ρ is an intrinsic property of a material and directly proportional to the total resistance R, an extrinsic quantity that depends on the length and cross-sectional area of a resistor.
